APPARATUS FoR BURNING GAS.

SPECIFICATION forming part of Letters Patent No. 267,971, dated November 21, 1882.

A Application filed April 3, 1882. (No model.)

To all whom t may concern:

Be it known that I, GEORGE H. BURRows, of Somerville, in the county of Middlesex, of vthe State of Massachusetts, have invented a new and useful improvement in Means or Apparatus for Burning Gas for the Illumination orV y; HeatingofObjects; andIdo hereby declare the same to be described in the following specification and represented inthe accompanying ro drawings, of which- Figure 1 is a top view, Fig. 2 a front elevation, and Fig. 3 a vertical and transverse section, of an apparatus embracing my invention, the nature ot' which is deiinedin the claims hereinafter made.

In the said drawings', A A A A denote a series of gas-burners arranged around a gas-heater, B, and communicating with the lower part of such. This gas-heater consists of a cylindrical and tubular standard, a, surmounted by a hollow globe, b, and having within it an induct,c, to extend from the bottom cl of the standard up nearly to the top of the chamber or space within the globe. `The standard is '25 provided at its lower end with a`female screw, c, to secure it upon a gas-pipe, so as to enable gas therefrom to pass intothe inductc, and from thence upward into the hollow globe and down within the standard to and into each of the burners. rIhe globe should be arranged at a height which will insure it being heated to the best advantage by heat radiated from the inner surfaces of the dames of the jetsof the burners. The gas in flowing into and down within the heater B becomes very highly raised intemperature, so that .on being discharged from the jets its combustion becomes much easier or greatlyfacilitatedand improved, the carbon ofthe gas being almost if not entirely consumed, and in consequence thereof theame is rendered brighterin color and possessive of increased lightgiving properties. Furthermore, in a very short time after intlaming the gas at the burners the heater becomes so highly raised in temperature that should the ameof any 011e of the burners be suddenly extinguished by a current of air the effluent heated gas from such burnerwill generally be at once relighted or inflamed by the heater.

5o The globe of the heater, on its external surface, I usually make light-reflecting like a mirror. To accomplish this, when the body of the heater is brass or iron, I nickel-plate it on the outer surface of the globe especially, if not on the entire outer surface of the heater, and l brightly polish the metallic covering. In this case the heater is made not only to perform the function of absorbing heat radiated from the flames of the burners, but of reflecting or dispersiug in directions radial to its globe therays 6o of light proceeding from the inner sides ofthe llames ofthe burners.

A compound gas heater and burner as above described can be employedto great advantage and with highly economical results in produc-l ing light from illuminating-gas.

By encompassing each of the burners with a conical sleeve to direct air to the dame the heating power of the flames will be increased,

though at the expense of their illuminating 7o powers, in which case the apparatus can be used to advantage as a heater.

I am aware of the gas heater and burners as shown and described in the United States Patents numbered 249,063 and 251,102, in each of A which the gas enters at the top of the heater and passes downwardthrough the said heater, and thence downward out of such by a pipe or pipes before reaching the burner or burners 5 but in my apparatus the gas enters by an in- 8o duct extending upward within the heater from its bottom, and thence passes downward within the heater to the burners,A the heater being entirely closed at top. Therefore with my apparatus there is no pipe extending above the S 5 heater in a manner to intercept the light, and

. thereby cause shadow; and, besides, :my heater in its upper part is a hollow globe, or substantially such, and has its outer surface lightreflecting, to disperse in all directions radially 9o from it, and particularly from its upper part, the rays of light that may fall on it from the dames ofthe burners.

I would further remark that my burner differs very materially from either of those shown in S. Andrews7 patent, dated April 15, 1831, and in the United States Patents numbered 26,888 and 253,003, in which the gas-jets are arranged to produce a continuous and practically circular or tubularilame,which, by encompassroo of the heater.

ing the heater, prevents light from being reiiected therefrom, as it is by the globular part of my heater; and, besides, the heaters of such patents are notrelleotors, asis that of my abovedescribed burner. In my invention the gasburners are separate from each other and arranged at intervals apart, so as to enable reliected light to pass between them and their flames, the rays of light being reflected upward as well as downward by the globular reflector Such burners also have their tips or upper ends placed in or near the central horizontal plane of the globular rellector.

I would further state that I do not .confine my invention to four burners, as shown, as any other suitable number ot' them may be used with the heater.

What I claim as my invention is as follows,

viz:

1. The improved compound gas heater and burnerconstructedsubstantiallyas describedviz., with the heater closed at top and with the gas-induct to extend upward within the heater from its bottom nearly to its top, in combination with a series of separate gas-burners arranged about the heater and with intervals or spaces between them, as shown, to lead or open out of its lower part, and having their tips or upper ends placed in or near the central horizontal plane of the globular reflector, allessenti llyas set forth.

2. he described compound gas heater, burner, and light-rellector, consisting of the gasheater, having a light-reilecting outer sur- -face, and the induct and series of separate gasranged to extend upward within such heater,

and with a series ot' separate gasburners arranged around the heater and apart from each other and leading out of its lower part, and having their tips or upper ends placed in or near the central horizontal plane of the globular reflector, all being substantially as set forth.
